Normal physiological levels of ceramide are necessary for glucose homeostasis; inhibiting ceramide synthesis in lean mice causes glucose intolerance and insulin resistance.

While blocking ceramide helps obese mice, it can harm lean mice by causing insulin resistance, suggesting a 'Goldilocks' zone for ceramide levels.

ModerateQualifiesMEDIUM confidence
inhibition of de novo ceramide synthesis in lean C57BL/6J mice on a normal chow diet also led to modest glucose intolerance and insulin resistance... This may suggest that normal physiological levels of ceramide are necessary to maintain glucose homeostasis and that either increasing (as in obesity) or decreasing ceramide biosynthesis from this physiological threshold may impair glucose homeostasis.

Why this rating

Observed in lean mice, which is a different population than the primary obese models.
